CONDENSER

MECHANISMThe motor rotates the shaft and forces the piston to and fro compressing the air in the tank. As it is an adiabatic process the internal energy remains constant and temperature of the system(air & steel tank) rises. As the water surrounds the tank the heat from the system spontaneously flows to it. Hot water will then rise higher against cold water and move into the water tank and cold water will flow down in the condenser. Ones the pressure in the tank has crossed its limit the air will flow to the cylinder, immersed in water, containing piston attached to a shaft connected to a dynamo. As the pressure will increase the piston will rise, rotate the shaft, and make the dynamo work producing D.C. current. Ones the piston has moved to the highest position the cooled air is then ready for use. When one of the two pistons has raised up the other will simultaneously move down. The flow of air in either of the cylinders will be regulated by an electrically controlled valve. This alternate motion will help work the dynamo and produce current. The current could be stored in a storage battery and used via inverter.

WORKING

PRIMARY COOLINGWhen the air is compressed in the tank the pressure increases keeping volume constant. As we know ‘PV=nRT’, where ‘ΔV=0’. Thus ‘n’(no. of moles) increases, and correspondingly the energy associated with ‘n’ also increases. Due to the increase in internal energy of the system, having constant volume, the energy density increases and temperature raises rapidly. This excess of heat spontaneously flows to the walls of the steel tank. The heat is then absorbed by the water(in condenser) surrounding the tank. During this process only air will be cooled and water will be heated but no electricity will be generated.

SECONDARY COOLING

When the air pressure in the tank crosses its limit the air will move in either of the cylinders pushing the respective piston up. These pistons are connected to the shaft which makes the dynamo work via gears. This air has to do some work to push the pistons higher. This work is converted into electrical energy. As all the energy can’t be converted to electricity, some energy gets converted into thermal energy which is again absorbed by water. In this process electricity is regenerated and air is cooled again.
